A warming hiatus has occurred in many high-latitude regions in recent decades, but its impacts on tree growth in the southern boreal forest remain unclear. We sampled tree rings of Dahurian larch (<em>Larix gmelinii</em>) in the southern boreal forest of the Greater Khingan Mountains (GKM) and examined the trends of tree growth and its temporal stability based on the age-detrended basal area increment (BAI) for the periods of rapid warming (1962–1992) and warming hiatus (1993–2022). The results indicate that age-detrended BAI declined significantly during the warming period, while it showed no further decrease during the period of warming hiatus. Tree growth decline was associated with higher daily maximum air temperature in the main growing season and daily minimum air temperature in the non-growing season, as well as lower precipitation in the early growing season and daily minimum air temperature in the main growing season. During the warming hiatus, tree growth was positively regulated by the precipitation in the non-growing season, daily maximum air temperature in the early growing season, and daily minimum air temperature in the main growing season, but negatively affected by the daily maximum air temperature in the late growing season. Intriguingly, tree growth stability declined significantly during the warming period and recovered rapidly during the period of warming hiatus. The decline in tree growth stability was mainly explained by increasing daily minimum air temperature in the non-growing season. The recovery of tree growth stability was associated with lower precipitation in the non-growing season, higher interannual stability of daily maximum air temperature in the early growing season, higher interannual mean value and stability of daily maximum air temperature in the late growing season, and lower interannual mean value and stability of daily minimum air temperature in the main growing season. Our findings highlight a rapid recovery of tree growth stability instead of growth rate during the warming hiatus following a period of rapid warming and provide new insights into the decadal-scale resilience of the southern boreal forest in response to climate change.</div></div>","PeriodicalId":54270,"journal":{"name":"Forest Ecosystems","volume":"15 ","pages":"Article 100418"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145813932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the role of canopy species identity and diversity on leaf litter decomposition in forests remains understudied. By controlling for macroclimate, soil properties, and litter substrate in a mature common garden, we investigated whether a three-month tea bag incubation of standardized green and rooibos tea substrate is driven by canopy tree species characteristics and diversity. Our study hypothesized two primary pathways: a chemical engineering effect, where trees alter soil properties and decomposer communities through litter input, and a physical engineering effect, where tree canopy structure modulates the local microclimate. The results showed that even under uniform macroclimatic and initial soil conditions, mass loss rates varied widely for green tea (27.4%–73.2%) and rooibos tea (6.1%–34.7%), comparable as found in other research between distinct biomes. While substrate quality was the dominant factor, both engineering pathways and, to a minor extent, tree diversity modulated mass losses. For green tea, tree chemical and physical characteristics seemed equally important, while the physical environment showed an increased importance for rooibos. Incubation depth played a key role, where forest floor decomposition rates are more susceptible to temporal climate variations, and soil-layer decomposition rates are less susceptible to climate variations and more determined by tree species identity. Our findings suggest that tea bag experiments focusing solely on topsoil burial may underestimate processes in the forest floor and the mineral-organic boundary layer. This study underscores the critical role of litter substrate quality in decomposition while demonstrating that tree community composition and the associated herbaceous layer, through both chemical and physical engineering pathways, strongly modulate decomposition rates.</div></div>","PeriodicalId":54270,"journal":{"name":"Forest Ecosystems","volume":"15 ","pages":"Article 100387"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mill.) monitored weekly across 33 plots from 2018 to 2022 in Montmorency Forest, Quebec, Canada. Wood microcores were collected from April to October to quantify the timings of cambial activity and xylem development on anatomical sections observed at high magnification under the microscope. The first enlarging cells appeared between late May and early June (day of the year (DOY) 153–167), and cell-wall thickening ended in late August (DOY 223–238), resulting in a growing season of 63–79 days. Xylem production ranged from 27.4 to 47.9 radial cells. While the onset of xylogenesis was well synchronized among individuals, within 2 weeks, the cessation of growth showed a greater variability, reaching up to 3 weeks. This autumnal variability was positively correlated with wood production, as higher cambial activity increases the accumulation of xylem cells to be differentiated. Our findings provide empirical evidence that individual variability in growth cessation reflects the underlying heterogeneity in cambial activity among trees of the same stand. Our results demonstrate the role of xylem phenology, especially during the autumn, in shaping forest growth. The assessment of both seasonal and individual variability in phenology is an essential step to improve the representation of autumn processes in forest carbon models, which can help to reduce the uncertainty in predictions of boreal forest growth under current or future climate scenarios.</div></div>","PeriodicalId":54270,"journal":{"name":"Forest Ecosystems","volume":"15 ","pages":"Article 100414"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145697237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reason for this trend often remains elusive, but it can be shown that it is a direct consequence of, deliberately or by mistake, adopting a design-based inference perspective when evaluating the results from model-based predictions. However, the design-bias trend is problematic in many applications, because the real conditions within the ecosystem studied will not be correctly determined. Instead, predictions tend to be shrunk towards the mean value of the target variable in the sample data used for estimating the parameters of the prediction model. Thus, calibration techniques to mitigate the design-bias trend have been proposed by some authors. In this article, we evaluate various regression techniques with respect to bias. The method of evaluation is founded on design-based inference, and thus, with regard to terminology, the regression techniques are used for estimating fixed quantities at the level of population elements rather than for predicting random quantities, as in the case of model-based inference. With aerial laser scanning data or digital aerial photographs, standard ordinary least squares (OLS) regression combined with classical calibration (CC) and the new MAVGAR method performed best in terms of bias, and produced good or reasonably good root mean square error (RMSE) values. The MAVGAR method aims to minimize the mean of the absolute values of groupwise average residuals, which is the origin of its name.

This study models the dynamics of Italian silver fir (<em>Abies alba</em>) forests under varying climate change scenarios using the forest gap model FORMIND. Focusing on three distinct silver fir provenances (Western Alps, Northern Apennines, and Southern Apennines), the study simulates forest growth in the Tuscan-Emilian Apennine National Park under different representative concentration pathways (RCPs). The individual-based model FORMIND was parameterized and validated with field data for each of the provenances, demonstrating its ability to accurately reproduce key forest metrics and dynamics. Our results reveal significant differences in expected growth patterns, productivity, metabolism, and carbon storage capacity among the silver fir provenances in pure and mixed stands. In the simulations, the Northern Apennines provenance showed higher biomass production (biomass &gt;10% ​± ​1%) and carbon uptake (net primary productivity, NPP &gt;8% ​± ​1%) at the end of the century compared to the Western Alps provenance in the pure provenance (PP) and no regeneration scenario. Conversely, the Southern Apennines provenance showed higher biomass (biomass &gt;5%–10%) and NPP (&gt;15%–18%) in mixed provenance (MP) and regeneration scenarios. These results show that genetic diversity strongly affects forest growth and resilience to environmental changes. Hence, it should be included as a predictor variable in forest models. The study also demonstrates the resilience of silver fir to climatic stressors, emphasizing its potential as a robust species in multiple forest contexts. The integration of forest provenance data into the FORMIND model represents a significant advancement in forest modelling, enabling more accurate and reliable predictions under climate change scenarios.
